Many investors assume that being "green" always helps financial returns in real estate. But recent research suggests the relationship is more nuanced. A new study on global Real Estate Investment Trusts (REITs) shows that lower carbon emissions generally correlate with higher profitability — yet this link depends heavily on where the REIT is headquartered.
The study: 375 REITs across seven years
The research analyses 375 REITs from 2017 to 2023 across 21 economies, examining how environmental performance — especially carbon emissions — relates to financial returns including operating margin, return on equity, return on assets, and return on invested capital.
The main findings are:
- Lower carbon emissions generally correlate with higher financial returns.
- But the strength of this relationship varies significantly by geographic location.
- REITs in major urban areas see weaker financial benefits from being green.
- REITs outside major cities show a stronger link between sustainability and profit.
- Reduction of indirect (Scope 2) emissions appears especially important outside cities.
These results suggest that sustainability and profitability are connected, but not in a simple, one-size-fits-all way.
Why location matters: urban REITs face extra constraints
The paper identifies three mechanisms through which urban density weakens the green–profit relationship:
| Factor | How it affects green REITs in cities |
|---|---|
| High operational costs | Urban properties often have higher running costs, which can offset the financial gains from efficiency and emissions reductions. |
| Regulatory standardisation | In many cities, environmental rules are already strict and uniform, so being "ahead of the curve" gives less competitive advantage. |
| Systemic environmental issues | Urban areas face broader challenges — grid constraints, congestion, and shared infrastructure limits — that individual REITs cannot fully control. |
In short, urban REITs are operating in a more complex, cost-heavy environment where being green does not automatically translate into a large profit premium.
Outside major cities: a stronger green–profit link
For REITs located outside major cities, the connection between sustainability and profitability is significantly stronger. In these contexts, green initiatives can create a clearer competitive edge, cost savings from energy efficiency are more visible, and the reduction of Scope 2 emissions plays a particularly important role.
This suggests that in less dense areas, environmental performance is a more direct driver of financial performance — and non-urban REITs may benefit from greater flexibility in adopting independent clean energy solutions.
Scope 2 emissions: the key indirect factor
The study identifies Scope 2 emissions — emissions from purchased electricity, heating, and cooling — as the critical driver of financial performance. For REITs outside major cities, reducing Scope 2 emissions often means improving energy efficiency in buildings, leading to lower utility costs, higher net operating income, and valuations that reflect lower climate risk.
For urban REITs, the same improvements may be less financially impactful due to the cost and regulatory environment described above.
The profitability benefits of environmental performance are primarily driven by Scope 2 emissions — particularly among REITs headquartered outside major urban agglomerations.
How AI could bridge the gaps
The paper highlights that advances in artificial intelligence offer opportunities to strengthen the environmental-financial link — particularly in dense urban contexts where that link is currently weakest. Specific applications include:
- Emission monitoring — AI can process large volumes of energy and emissions data, spot anomalies, and provide real-time portfolio-level insights.
- Resource optimisation — AI-driven systems can adjust heating, cooling, and lighting based on occupancy and weather, reducing unnecessary energy use.
- Predictive maintenance — machine learning models can identify underperforming assets before they become compliance or financial liabilities.
- Data-driven underwriting — AI tools that integrate emission data with financial performance can improve investment decisions across geographies.
Why this matters for investors and policymakers
The findings underline the need for spatially sensitive policies that consider how urban density impacts the economic viability of low-carbon transitions in real estate.
- Investors should not assume that green REITs will always outperform everywhere. Location matters.
- Asset managers may need to tailor sustainability strategies to local context — urban versus non-urban.
- Policymakers should consider that environmental incentives in dense cities may need to be designed differently than in less dense areas.
This research adds to the growing evidence that ESG performance in real estate is not just about being green — it is about where you are green.
